MOTION-TRANSLATING DEVICE.

Original application led April 28, 1920, Serial No. 377,262. Divided and this application led February 4, 1921. Serial No. 442,537.

To all wim/nt t v'zag/ concern.' y

Be it known that I, BENGT M. W'. HANsoN, a citizen of the United States, and a resident of Hartford, in the county ofv Hartford, State of Connecticut, have invented certain new and useful Improvements in a Motion- Translating Device, of whichv the following is a specification. s

This application is a divisional of my original application Serial No. 377,262 filed April 28th, 1920, for metal working machine.

The present invention relates to :a device for translating or converting motion, for instance, converting the reciprocating movement of one member into rotary motion of another.

As an instance of a use to which the de vice of the present invention may be placed, reference may be had to my aforesaid application wherein vis disclosed a metal working machine having a reciprocating tool carriage and a pivoted work support, the work support being rocked, to feed the work to the tool, by means of a cam which derives its rotary motion from the reciprocating carriage through the device here described and claimed. lt is, of course, to be understood-that the disclosure is by way of illustration only and is not to be taken as restrictive, for the structure is capable of various embodiments and is susceptible of different uses.

Inl the accompanying drawing:

Fig. 1 is a view in front elevation, with parts broken away7 of the device of the present invention. y y

Fig. 2 is a side view taken in vertical section through the structure shownin Fig. 1.

Referring tothe drawings in detail, a denotes generally a base orvpedestal of a machine such, for instance, as is shown in my original application; b, a reciprocating carriage adapted to support a tool, and c, ashaft which derives its rotary movement, through the device of the present invention, from the reciprocating movement of the tool carriage. This shaft may be connected up as described in my original application to the rotary feeding cam for the work support.

Referring now to the device of the present. invention, secured to the carriage b is a 4plate 10 to which is pivoted for angular ad- `iustment a guide member 11 adapted to be locked in position by a screw 12. In the Outer face 0f this guide member iS a clovethe teeth of the ratchet wheel.

tailedr groove 13 in which works a block la detachably connected by means ofa pin 15 to the head of a frame 17 mounted for reciprocating movement within a casing 18 secured to the pedestal of the machine. This frame has a pair of opposed racks 19, 20, one on each side'of the shaft 0. Adapted to be liXed tothe shaft c by means of a clutch 16 is a ratchet wheel 22 having a hub 23 at each side upon which are freely mounted segmental gears 24E, 25, meshing with the respective racks 19, 20.` Each of these segmental gears has an arm pivotally carrying a pawl 26 both of which are headedL in the same direction and held in engagement with the ratchet wheel 22 by springs 27 or otherwise. The frame 17 is normally urged upwardly byy a spring pressed plunger 28.

lt will be readily observed that with the structure described,` when the tool carriage.

tion and through the pawl carried by the arm of this gear the ratchet wheel together with the shaft c will be rotated clockwise. ln the meantime, the rack 19 is rotating the segmental gear 24 counterclockwise, and the pawl 26 fixed to this gear rides freely over When the tool carriage moves to the left, the frame 17 will move upwardly and the rack 19 rotates the segmental gear 24 clockwise resulting in rotation of the ratchet wheel and the shaft c in the same direction as when the frame 17 was lowered. Thus, on movementof the tool carriage in either direction, the shaft c will be rotated clockwise. The rate of rotation of the shaft c may be varied by angularly adjusting the guide member 11. When it is desired to manually rotate the shaft c by means of the hand wheel 7L, the sleeve 29 to which this wheel is fixed is pulled outwardly, thereby disengaging the clutch 16 and thus disconnecting the ratchet wheel 22 means of the pin 15, to one end ot a lever 30 of a mechanism vvhich is actuated only when the tool carriage reaches the ends of its strokes. It Will be seen that the other `end of the lever 30 is connected through linlr 31, bell crank lever 32 and link to aV lever 34: pivoted, as shown, to the pedestal a and having its upper end positioned between a pair of dogs 35 adjustably mounted on the carriage b. The lever 30 is slotted, as shown', to receive the pivot pin 36 so as to permit the level' 30 under the influence of a spring 37 to be drawn out of the Way oix the frame when this :trame is connected to the block 14.

I claim as my invention 1. A reciprocating member, a rotaryisha'ft, andl means therebetween for converting' the reciprocating movement of said member into the rotary movement of the shaft and includinga guide on said member having `au inclined' groove', a block slidably mounted in said groove, a frame mountedfor reciprocating movement and connected to said block, and means between said frame and shaft tor rotating the latter.

2. A reciprocating member, a rotary shaft, a motion translating device for converting the reciprocating' movement of said member into rotarymovement of said sha-ft, means carried by the member and adapted to be detachably connected to said device for uniformly rotating said shaft during the reciprocation of said. member, and means adapted to be detacliably connected to said device and'actuated'bysai'd member at the end of each; of its strokes for rotating said shaft step by step.

3. A reciprocating member, a rotary sha-it, a moti-on converting device associated with said shaft and including a reciprocable frame, a guide carried byl said reciprocating member and having a groove, a vblock slidably mounted in said lgroove, means inclu'ding a. lever actuated by said' reciprocating member at the end of each oi' its strolf. and' means for detachabl'y connecting said lever or said block to said frame.

4. A reciprocating member, a rotary shaft, and means therebetween for converting the reciproeating` movement of' said member into rotary movement of sai'd shaft and comprising' a guide member adjustably mounted on said reciprocating member and having a groove, ablockslidably mounted in said groove, a reciprocating Jframe connected to' said block and having a pair of racks, a ratchet ivheel fixed on said shaitt, a pair ot segmental gears loose thereon, one for each rack, and a pawl on each segmental rack `cooperating with said ratchet Wheel.
